* 'tty-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (65 commits)
tty: serial: imx: move del_timer_sync() to avoid potential deadlock
imx: add polled io uart methods
imx: Add save/restore functions for UART control regs
serial/imx: let probing fail for the dt case without a valid alias
serial/imx: propagate error from of_alias_get_id instead of using -ENODEV
tty: serial: imx: Allow UART to be a source for wakeup
serial: driver for m32 arch should not have DEC alpha errata
serial/documentation: fix documented name of DCD cpp symbol
atmel_serial: fix spinlock lockup in RS485 code
tty: Fix memory leak in virtual console when enable unicode translation
serial: use DIV_ROUND_CLOSEST instead of open coding it
serial: add support for 400 and 800 v3 series Titan cards
serial: bfin-uart: Remove ASYNC_CTS_FLOW flag for hardware automatic CTS.
serial: bfin-uart: Enable hardware automatic CTS only when CTS pin is available.
serial: make FSL errata depend on 8250_CONSOLE, not just 8250
serial: add irq handler for Freescale 16550 errata.
serial: manually inline serial8250_handle_port
serial: make 8250 timeout use the specified IRQ handler
serial: export the key functions for an 8250 IRQ handler
serial: clean up parameter passing for 8250 Rx IRQ handling
